TRANSLUMINAL TISSUE MARKERS

摘要

Methods and devices are provided for marking tissue to be subsequently locat ed for removal from a body or for other examination. In general, a marker is provid ed that can be delivered through a tissue wall proximate to tissue desirable for marking. T he marker can be movable between a non-deployed or unexpanded position, in which the marker i s configured to be delivered through a relatively small diameter passageway, to an expanded, balloon-like position in which the marker is configured to engage opposed sides of a tiss ue wall proximate to the desired tissue. The marker can remain disposed in the body in its expand ed position and be subsequently palpably identified and/or visually identified to locate the desired tissue.
